Fig. 5 is a bottom plan view showing my ornamental member assembled with a modified form of construction of the locking member; and

Fig. 6 is a section taken along the line 6-6 of Fig. 5.

The main object of my invention is the provision of an ornamental lock operating member of simple construction which may be easily as- ,5 sembled as part of a locking device of the type adapted to be secured to one frame member and having a yieldable catch device which is separab-ly engageable with a catch element on another frame member to maintain a pair of frame mem- Q hers in closed position in the manner familiar to those skilled in the art.

Referring to the preferred embodiment of my invention as illustrated in Figs. 1-4 of the drawing, I have shown a preferred form of ornamental 5 member l assembled with a locking member 2 through means of a clamping member 3. My preferred form of ornamental member is made of ribbon-dike sheet metal formed through bending a blank transversely thereof intermediate its ends to form a part of any desired shape having an operating portion adapted to be grasped by the fingers of an operator for actuating the yieldable catch device of the locking member for separating the frame members and a base means which is adapted to be clamped in assembly with the look-- ing member. In my preferred form of ornamental member, illustrated in Figs. 1-4, the material intermediate the free ends of the member is bent into a finger-operating portion ,4 of pleasing design with free end portions 5 extending in wardly toward each other beneath the fingeroperating portion to form a base (Fig. 2). The outermost free ends of the end portions 5 may be separated one from another, as most clearly shown in Fig. 2.

The locking member 2, which represents one of the forms of locking member with which I have chosen to illustrate my invention, is of the type adapted to be securely assembled with a bag frame member through snapping the locking member through an opening in a Wall of the frame member. The locking member 2 has a plate-like flange portion 6 at one end adapted to be disposed above the bag frame structure when the locking member is in final attached position, a base portion '1 at an opposite end from the plate like portion 6 (Figs. 2 and 4) and a yieldable intermediate portion 8 connecting the portions 6 and 1. The plate-like portion 6 may have a downwardly-extending lug portion 9 (Figs. 2 and 4) for engagement with a cooperating fastener elementon a mating frame member (not shown) to hold the frame members together. The looking member 2 has a pair of shouldered resilient attaching portions H3 (Figs. 2 and 4) extending from the base portion 1 and offset laterally relative to the intermediate portion 8. As a result of the offset relation of the attaching portions and the intermediate portion, the intermediate portion is permitted to yield back and forth relative to the attaching portions for engaging and disengaging the cooperating fastener elements provided for closing the frame members. The attaching portions 10 are adapted to contract during passage of the same through an aperture of a wall of a frame member (not shown) during attachment of the looking member to the frame member and then expand to engage their shoulders Ill behind material of the wall adjacent the aperture to fix the sembly with the frame member.

The clamping member 3, adapted to secure the ornamental member 4 with the plate-like portion 6 of the locking member, comprises an elongated body portion I! which is of substantially the width of the end portions 5 of the ornamental member and is provided With flange portions l2 integral with opposed longitudinal edges of the body portion H and extending from the body portion in substantially spaced parallel relation so as to form a channel.

Assembly of the component parts of my locking device is a relatively simple matter and may be carried out through first moving the clamping member with the flange position axially relative to the ornamental member to position the free end portions 5 of the ornamental member within the channel of the clamping member. Then the free end portions 5 are disposed adjacent the top surface of the locking member in secure asportions I 2 in full open clasp member plate-like portion 5 of the locking member prior to assembly of the locking member with a frame member and, finally, the flange portions l2 of the clamping member are crimped inwardly by any suitable tool to clamp the plate-like portion 6 and the free end portions 5 in secure assembly one with another, as most clearly shown in Figs. 3 and l. The locking device is now complete and may be attached to a frame member in the manner hereinabove described.

Referring to Figs. 5 and 6 of the drawing, I have shown my ornamental member assembled with a modified form of locking member l3 which is preferably formed from a single piece of metal and includes the clamping member and the looking member as a unit. My modified locking member I3 is adapted to be hingedly secured upon one of a pair of bag frame members and so arranged as to automatically rise and receive a cooperating fastening element upon a mating frame member when the frame members are pressed together and prevent their separation until manually operated. The member [3 preferably comprises a flat body portion l4 having a rear wall portion l5 integral with an edge of the body portion. Material adjacent the free edges of the wall portion is extends outwardly from the wall portion and then inwardly to provide loop portions H3. The free ends of the loop portions l6 are joined together, in my preferred form, by an intermediate connecting portion I'l extending in substantially parallel relation to the wall !5 for purposes of strengthening the hinge device. A lug 18 may extend from the wall l5 intermediate the loops iii-46 and engage the exposed surface of the connecting portion IT to hold the intermediate portion in proper fixed position relative to the wall portion. The loop portions l6l6 are adapted to pass through openings in the wall of a bag frame (not shown) and receive within them portions of a torsion spring (not shown) which operates to press the clasp body tightly downwardly holding a portion of the clasp in engagement with a cooperating fastener element of another frame member (not shown) in a manner well known in the art.

The ornamental member, used in combination with the clasp member I3, is similar in form to the ornamental member shown in Figs. 1-4 but having relatively shorter end portions 5. In order that the ornamental member may be securely assembled therewith, the clasp member of the locking device is provided, in my preferred form, with a flange portion l9 integral with the entire length of an edge of the body portion I4 opposed to that from which the wall portion l5 extends and extending in substantially perpendicular relation to the plane of the body portion 14. On each side of the wall portion I5 I have formed flange portions 28 extending from an edge of the body portion M in substantially parallel relation to the flange portion l9 whereby they cooperate with the flange ill to form a channel. In assembling the ornamental member with the Hi, the free end portions 5 of the ornamental member are disposed within the channel formed by the flange portions 20 and I9 and then by any suitable tool the flange portions 20 and is are crimped inwardly to clamp the end portions 5 in engagement with the body portion l4 so as to secure the parts in firm assembly, as most clearly shown in Fig. 6. When the completed locking device is assembled with the bag frame member, a portion of the flange l9 may provide a lip for receiving a cooperating catch element of the mating frame member for holding the frame members in closed position.

Thus by my invention I have provided ornamental members of simple construction and pleasing design which may be quickly and easily assembled with many forms of locking members to provide a compact and efficient locking device. The specific ornamental members hereinabove set forth are particularly adapted for use with locking members of the type illustrated and described, but it should be understood that my ornamental members may be equally well applied to other locking members for bag frames and the like.

Although I have illustrated and described preferred embodiments of my invention, I do not wish to be limited thereby because the scope of my invention is best defined by the following claims.

I claim:
